Abstract
870,075. Percussive tools. MINE SAFETY APPLIANCES CO. July 16, 1958, No. 22900/58. Class 124. A dust collector comprises a bracket for connection to a support, a sleeve rotatably disposed axially in the bracket and loosely receiving a drill stem, a coupling ring detachably secured round the sleeve and supported by the bracket, the sleeve and ring having registering radial openings for connection to a suction line. As shown, a bracket 18, secured to a support 20 comprises a pair of retaining rings 22, 24 having a sleeve 30 journalled therein. A coupling ring 32 encircles the sleeve 30 between the rings 22, 24 and, by means of a set screw 33, prevents axial movement of the sleeve. The sleeve 30 and ring 32 have registering radial slots, that on the ring being connected to a suction conduit 39. A resilient hood 27 is fitted to the outside of the ring 22 and provides an air-tight joint with the surface being drilled. A drill stem 14 fits loosely within the sleeve 30 and air may be drawn through the annular space between sleeve and stem to draw dust out through the conduit 39. Specification 870,074 is referred to.
